Description of functions
The conveying system
PFT SILOMAT E 140 VAE
is a pneumatic, fully automatic conveying
system for transporting ready-mix dry mortar from the silo / container to the cleaning machine.
Please observe the processing guidelines of the material manufacturer.
The machine consists of portable or transportable components, which facilitate rapid transport in
convenient dimensions.
The following points should be observed during operation:
¾
Worksite power connection – control box
¾
Control box connection – level sensor
¾
Control box connection – motor and drive
¾
Control box connection – vibrator
¾
Compressor connection – conveying container
¾
Conveying container connection – cleaning machine
Operating sequence
As soon as the level sensor of the cleaning machine reports “Empty”, the flap opens (“Open”
position) and the conveying container is filled with approx. 62 l of dry material while the silo
butterfly valve is open. The vibrator runs at the same time in order to support the flow of material
from the silo / container.
When the filling time has elapsed, the flap closes again (“Closed” position). The conveying
container is now sealed pressure-tight to the silo / container.
Now the compressor begins to work and blows air through the emulgator filter into the conveying
container. In this way, the material is loosened up and pressed through the extraction connection
(16) of the conveying container into the conveying line and on to the cleaning machine. Pressure is
built up in the conveying line, which is monitored with a safety switch. If it drops below the set value
of 0.5 bar, this means that the conveying container and conveying line are empty. The system
completes the conveying cycle and shuts down. As soon as there is a new signal from the level
sensor at the control box of the SILOMAT E 140, a new conveying cycle is started.
The distribution of air can be controlled by hand using the bypass at the conveying container. In
this way, the system can be adapted to suit the material (specific weight) in question.
Intended use
The compressor can be used to generate overpressure.
Operation is only designed for normal atmospheric air. Not for the conveying of toxic or
combustible media. The compressor works oil-free. Avoid the intake of oil mist. The characteristic
data are valid up to a height of 800 m above sea level.
